“…and ∆E = (nCA/Ba) total energy -n.(CA) total energy -K 2 (3) where n is the number of Li + ions (1,2) or is the number of CA molecules (1, 2, 3) in the complexes. As K 1 and K 2 are constants, which are irrelevant to comparison of the different complexes, they were set to zero; K 1 = (CA) total energy + n.(H + ) total energy and K 2 = 2.…”

“…A deeper understanding of complexes between α-hydroxycarboxylic acids and metals (M) that are formed on those routes is desirable, since these compounds are highly effective in obtaining heterometallic advanced ceramics 1 . Several metallic ions with different applications have been employed in this kind of route, such as lithium ion in the manufacturing of cathodes for fuel cells 2,3 and barium ion in pellets of high temperature superconductors [4][5][6] , magnetic materials 7,8 , and multiferroic materials 9 . The modified polymeric precursors method (MPPM) 1,4 involves the polyesterification process of a metal chelate complex using a hydroxycarboxylic acid and a polyhydroxy alcohol in an aqueous solution, which turns into a polymeric gel.…”

The performance of advanced electronic ceramics is directly related to the synthesis route employed. Sol-gel methods are widely used for this purpose. However, the physicochemical intermediate steps are still not well understood. Better understanding and control of these processes can improve the final quality of samples. In this work, we studied theoretically the formation of metal complexes between citric acid and lithium or barium metal cations with different citric acid/metal proportions, using Density Functional Theory electronic structure calculations. Infrared and Raman scattering spectra were simulated for the more stable geometric configurations. Using this methodology, we identified some features of complexes formed in the synthesis process. Our results show that the complexes can be distinguished by changes in the bands assigned to C=O, COH-, and COO -group vibrations. An estimate of the most stable complexes is made based on total energy.

Abstract. Monoclinic Li 1+x V 3 O 8 is an attractive cathode candidate for lithium-ion batteries. Here Li 1+x V 3 O 8 precursor was synthesized via a electrospinning process using LiNO 3 , NH 4 VO 3 and citric acid as raw materials, and followed by a thermal treatment at 450°C for 5 h in air atmosphere, to get well formed Li 1+x V 3 O 8 powder. The structure, morphology and electrochemical performance of the as-synthesized Li 1+x V 3 O 8 sample were characterized by X-ray diffraction (XRD), fourier transform infrared (FT-IR), scanning electron microscopy (SEM) and galvanostatic charge-discharge test. The effects of synthesis conditions on the structure and the electrochemical performance of the Li 1+x V 3 O 8 sample were evaluated and discussed. It showed a high initial capacity of 283.4 mAh·g -1 , and remained about 210 mAh·g -1 after 100 cycles.
